Приватные платежи на блокчейне Polygon: как ZK-доказательства стыкуются с регулятором

Приватные стейблкоин-платежи на Polygon: как ZK-доказательства стыкуются с регулятором 4 мая 2026 Polygon Labs объявил, что в Polygon Wallet добавлен пункт «Приватная отправка» (Privately Send) — отправка USDC и USDT с сокрытием отправителя, получателя и суммы транзакции. Технологический партнёр — Hinkal, протокол шифрованных пулов с верификацией через протокол доказательств с нулевым разглашением. Разбираемся, где слабые места в модели и почему этот паттерн важен далеко за пределами платежей — для RFQ-протоколов и опционов

PLONK: разбираем уязвимости криптографического протокола

Привет, Хабр! Я Ирина Слонкина из отдела безопасности распределенных систем, Positive Technologies. Вместе с коллегами исследую безопасность смарт-контрактов и блокчейн-приложений. Конечно, всегда интересно вникнуть вглубь каждой технологии, вышедшей на рынок. В этой статье я расскажу про криптографический протокол PLONK, один из самых интересных протоколов в блокчейн-индустрии.

ZK discourse turned into a glossary contest. SNARK vs STARK, proof vs argument… meanwhile almost no one models adversaries, composition, or real leakage. “ZK is free” and “Fiat-Shamir depends” in production is how systems break.

One of the pitches for Zettelkasten method is “conversing with your slipbox". I looked up a way to have an LLM augment my zk to let me query it with chat prompts and came across Reor.

(Readwise has a feature to chat with your highlights, but my highlights are too noisy. I keep notes that I want permanently separately in my zk.)

Reor looks like it does everything locally after downloading an Ollama model.

Im Januar 1990 öffnet sich der legendäre Panzerschrank 28 im #ZK der #SED – darin: Gold, Devisen, Schmuck und Millionen in bar. Doch schon wenige Monate später ist das Vermögen verschwunden.

Die zweite Folge der Reihe „Die #Milliardenjagd“ zeigt, wie die #SED / #PDS versuchte, ihr riesiges Vermögen vor der ersten freien Wahl in der #DDR zu retten – über geheime Konten, Mittelsmänner...

China's total car sales fell 12.1% YoY in Jan 2025 to 1.794M, but NEV sales grew 10.5% YoY to 744K (41.2% share). NEV production hit 940K (+25.8% YoY). The market shrank due to an early Lunar New Year and 2024 pull-ahead purchases, but NEVs keep gaining ground. 🚀 #ElectricVehicles #BEV #EVs #BYD #ZK
